The Bare Copper Wire Weight Calculator estimates the weight of copper wire based on its length and cross-sectional area. This calculation is essential for electrical engineering, manufacturing, and material planning.
The calculator uses the following formula:
Where:
Explanation: The formula calculates weight by multiplying the volume of copper (length × cross-section) by copper's density.
Details: Accurate weight calculation is crucial for material cost estimation, shipping logistics, and structural support requirements in electrical installations.
Tips: Enter length in meters and cross-sectional area in mm². Both values must be positive numbers. For round wires, cross-section = π × (diameter/2)².
Q1: Why is the density factor 8.89?
A: Copper's density is 8.96 g/cm³. The factor 8.89 accounts for unit conversion (mm²/m to cm³) and typical purity of electrical copper.
Q2: How do I calculate cross-section for round wire?
A: For round wire, use the formula: π × (diameter/2)² where diameter is in mm.
Q3: Does this work for stranded wire?
A: For stranded wire, use the total cross-sectional area of all strands combined.
Q4: How accurate is this calculation?
A: It's accurate for pure copper wire. Actual weight may vary slightly due to impurities or coatings.
Q5: Can I calculate length from weight?
A: Yes, rearrange the formula: Length = Weight / (Cross Section × 8.89).
